STAPLING-TOOL.

Specification of Letters Patent.

Patented Jan. 4, 1916.l

Application led October 17, 1911. Serial No; 655,146.

'pieces of light material together, which tool may be conveniently and quickly manipulated both to apply the staple and to release the same after it is applied.

A further aim of the invention is to provide an attachment for an ordinary shoe button applying tool or the like which will adapt the tool for use in applying staples, without in any Way interfering with its use as originally intended.l

A still further aim of theinvention is to provide means for firmly holding the Vstaple to be applied, in position, the means being readily operable to release the staple after its application.

With these and other objects in view the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claims, it being further understood that changes in the specific structure shown and described may be made within the scope of the claims, without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specication and in which like numerals of reference indicate similar parts in the several views: Figure 1, is a perspective view of the tool embodying the present invention. Fig. 2, is a vertical transverse sectional view through the ends of the jaws of the tool, showing a staple arranged thereon and about to be set. Fig. 3, is a top view of the leaf spring. Fig. 4, is a top view of the forward section of the staple holding member. Fig. 5, is a bottom .view of the upper jaw end. Fig. 6, is a perspective view of one of the staples.

In the drawings, the tool embodying the present invention is illustrated as consisting in part of two crossed pivoted handles, one of which is indicated by the numcml 1,

and the other by the numeral 2; The pivot for the handles is indicated by the numerall 3, and beyond the said pivot the handles are formed with jaws 4 and 5, respectively,

ment of the handles 1 and of each other. i

The upper jaw 5, of the tool is formed with a slot G, which enters from the outer end and communicating with oppositely p0- sitioned staple receiving recesses 7, which 2, in the direction open at their inner ends into the said Slot,v

as shownin Fig. 5. The back of the staple' to be set is seated in these recesses 7, and extends into the slot 6, as will be presently explained. That face of the lower jaw 4, which opposes the jaw 5, is formed with an upsetting recess 8, shown in Fig. 1, having a raised intermediate rib 9.

Secured to the upper side of the jaw 5, by a means to be presently explained, is a leaf spring 10, with apertures 9', formed in its end and this spring projects above the end of the said jaw and has an edgewise entering slot 11, as'shown in Fig. 3, and this spring has a normal tendency to spring away from the said jaw 5. The stapje holding device of the present'invention embodies a'rear member 12, which is secured to the jaw 5, by means ofva screw 13, threading therethrough and into the jaw. 5.y This Lscrew also passes through one of the apertiires 9', Within the spring 10, and serves to secure the two members in place. A stud 14, projects from the jaw 5, adjacent to the screw 13, through an aperture 9 and a suitable-opening formed in the member 12, and this stud serves to hold y these members against lateral displacement, ,as will be .reads ily understood. v

A spring leaf finger 17, is hinged as at 18,

to the forward end of the member l12, and is adapted to assume either the ,full line or dotted line position shown in Fig. 2, of the drawings. This finger is formed or provided at its hinged end with an ear 19, which is adapted to ride over the upper side of the spring 10, as the finger is swung from one position to the other, depressing said `spring 10. and holding the said finger in either of the illustrated positions by reasonl of its engagement with the said spring. At its free end, the spring Enger 17, is reduced in width and is twisted at its reduced portion, as indicated by the numeral 20, to forni a tongue 5', which is adapted to pro- 60 which are adapted to be closed upon movenotch 21, which is adapted' to register with the inner -ends of the notches 7, when the tongue f, of the finger is in position in the The staple adaptedto be 'set bythe 'tool above described,` is" clearly 4shown inv Fig'f 6,.V of the drawings, and includeslegs 22, andV a connecting portion 23, which.l isf'formed' withabightifv L I In usingthe tool, thestaple shown in Fig.-

64 is' disposed with its 'bight 24, seated in the siot 6, inthe jaw 5, and its' portions 23', en-

gagingV in the recesses 7. .The finger 17, is then depressed against the tensionof the. -spring 10, until the'bi ht i 'seated inthe notch 21, o the tongue 5. The,

finger is then released, whereupon the spring 10, will-force the finger upwar'dly,'thereby firmlyseating the bight of the staple in the manner stated. The staple lWilljthus' be held with theA free ends of its arms 22, Apresented towardv the upsetting notches'or recesses 8, in the jaw 4, and when the jaws are closed, the pieces to be secured having been inserted between the jaws, the said-ends of the. arms of the rivet will be forced through the pieces' to be secured and will be upset' by thewalls of the recess 8, and the raised portion 9,-

therein, in the manner illustrated in Fig. It, of the drawings. After the 'staple has been set, the spring 10, may be depressed by the thumb, whereupon the tongue will be released from the staple. It will be readily understood that by swinging back the finger 17, the tool may be used to set buttons, -and for other purposes.

'Having thus described our said invention, what we` claim as new. and desire to 'secure by United States Letters Patent, is:

1-. In audevice of the class-described, relatively movable jaw members, one of said members being formed with a vslot andthe .other member being formed with upsetting recesses, a spring secured upon the first mentioned member, and a finger hingedly connect-ed with the spring.and provided with a portion arranged to project through the said slot and having a notch to'receive the head of a staple or the like to be set, the

said spring being arranged to normally tend to swing .the said finger away from the `member upon which the spring is mounted.-

2. A tool embodying two crosswise pivoted handles, each formed with a jaw, one an upper and the other a lower jaw, said upper I jaw having an end-entering slot and also oppositely positioned staple receiving recesses communicating with said end-enterand having an edgewise entering slot, a rearl member secured to said upper jaw,A anda spri'ngleaflfinger hinged to said rear member and 'provided at its hinged end with an ear arranged to ride over` the upper side of said spring, said finger at its .free end being:

reduced-.,.inwidth and-twisted tozform a tongue arranged-toiproject through said leaf spring slot, andformed with a notch, all. arrangedgas and for the 'purpose set "3. Ina tool of the-kind described, a pair oflg'eop'e'rating pivoted jaws, one of said jaws 'being slotted `atits forward end, handles for operating said jaws, areslient member having a slot registering lwith the slot of said jaw, and a staple-carrying meme member secured to said slotted jaw, said ber bearing upon said resilient member and having a hook portion projecting through the s lot of said resilient member and yieldingly fitting' in the slot of said jaw.

4. In a tool of the kind described, a pair of coperating pivoted jaws, oneof said jaws being slotted at its forward end, han,-

dles for operating said jaws, ai leaf spring' secured on said slotted jaw, said spring having a slot registering with the slot of said jaw, and a staple-carrying member pivoted on said slotted jaw and bearing adjacent one end upon said-spring, said staple-carry-v ing member having a staple-engaging hook -i projecting through vthe slot of saidspring -and yieldingly fitting. in the slot of said jaw. j

5. In a tool of the kind described, upper and lower cooperating pivoted jaws transversely recessed on theirunder and upper faces, `respectively, said upper' jaw being longitudinally slotted at its forward end, handles for operating said jaws,` a leaf spring secured `on said slotted jaw, said spring havifg a slot registering with the slotI o said jaw, and a staple- 'carrying member pivoted on said slot.

ted jawand loosely bearing adjacent one end upon said spring, said staple-carrying member having a staple-engaging hook projecting :through -the slot of said spring and yieldingly fitting into the slot of said Jaw- 1 In testimony whereof we aix our signatures, in presence of two witnesses.
